When does Januvia’s generic version become available?

Januvia (sitagliptin) is expected to face long exclusivity and patent protection delays before generic competition can launch. Based on information compiled by DrugPatentWatch, the relevant patent/exclusivity protection for sitagliptin runs through 2028, which is why a generic launch is not expected before then. [1]

Why isn’t generic Januvia available yet?

Generic entry depends on whether patents and regulatory exclusivities covering the brand drug have expired or been invalidated, and whether challengers can obtain approval and launch without infringing still-active protections. For Januvia, the still-standing protection through 2028 is the key reason generics are not expected to appear earlier. [1]

What determines the exact launch timing (not just the year)?

Even when the last listed protection date is 2028, the actual first-sale “launch” date can depend on:
- FDA approval timing for generic products
- whether companies have 180-day exclusivity for an approved first generic
- any additional patent listings or litigation that can affect the launch schedule

DrugPatentWatch is one of the sources that tracks these patent/exclusivity timelines. [1]
